Description

Technical Field

[0001] This invention relates to the field of disinfection equipment technology, and more specifically, to an air and surface disinfection device that utilizes the synergistic effect of ultrasonic plasma and photo-oxidation. Background Technology

[0002] With the increasing global awareness of public health, especially given the frequent occurrence of viral transmission events in recent years, efficient disinfection of air and object surfaces has become an important requirement in fields such as healthcare, food processing, public spaces, and daily homes. Traditional disinfection methods mainly involve the use of chemical disinfectants.

[0003] Currently, traditional disinfection methods often leave chemical disinfectant residues on the environment or object surfaces after use, which may cause skin allergies, respiratory irritation, or other health risks. Long-term exposure may even lead to chronic toxicity problems. Furthermore, some emerging technologies, such as ozone disinfection and photocatalytic oxidation, require longer disinfection times and are often used in conjunction with atomization technology. Traditional atomization methods rely heavily on the atomization of chemical liquid reagents, resulting in a small atomization area and potential uneven atomization, thus affecting the disinfection effect.

[0004] Therefore, in view of this, we will study and improve the existing structure to provide an air and surface disinfection device with the synergistic effect of ultrasonic plasma and photo-oxidation, in order to achieve a more practical purpose. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this invention is to provide an air and surface disinfection device that combines ultrasonic plasma and photo-oxidation. It can achieve highly efficient disinfection in seconds, leaves no chemical residue, and does not produce chronic toxicity, thus ensuring the safety of disinfection. At the same time, it significantly expands the atomization coverage area, improves disinfection uniformity, increases the atomization area, and ensures the disinfection effect.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An air and surface disinfection device using the synergistic effect of ultrasonic plasma and photo-oxidation includes a disinfection host. The disinfection host has windows on its front and two sides. A fixed grille is fixedly installed on the window on the front. A control panel is fixedly installed above the front of the disinfection host. Adjustable grilles are installed on the windows on the sides. The disinfection host has an internal grille control component that controls the movement of the adjustable grilles.

[0010] The adjustable grid includes several horizontal grid plates and two vertical grid plates. The horizontal grid plates and the vertical grid plates are vertically distributed in space, and there is no direct contact between any horizontal grid plate and the vertical grid plate.

[0011] The grid control assembly includes a horizontal control structure and a vertical control structure. The horizontal control structure and the vertical control structure have the same structural composition. The horizontal control structure controls the rotation of the horizontal grid plate, and the vertical control structure controls the rotation of the vertical grid plate.

[0012] Furthermore, the lateral control structure includes a motor, the output end of which is connected to a sector gear via a coupling, and the sector gear meshes with a driven gear.

[0013] A rotating shaft is fixedly inserted through the transverse grid plate. One end of the rotating shaft is fixed to the central shaft of the driven gear, and a torque spring is installed at the other end of the rotating shaft. The torque spring is fixed to the inner wall of the disinfection host.

[0014] The lateral control structure also includes several thin connecting rods, each of which is hinged to two adjacent lateral grid plates.

[0015] Furthermore, the motors in the lateral control structure and the motors in the vertical control structure are controlled by independent signals.

[0016] Furthermore, both motors are equipped with electromagnetic brakes, and both motors are fixed inside the sterilization host.

[0017] Furthermore, the number of teeth of the sector gear occupies a sector angle of 120°.

[0018] Furthermore, in the lateral control structure, four thin connecting rods are provided between two adjacent lateral grid plates, and the four thin connecting rods are parallel to each other and distributed in a square.

[0019] Furthermore, the disinfection host is equipped with an ultrasonic generator, a plasma generator, and a UVC radiation generator.

[0020] Furthermore, a consumable inlet pipe is fixedly installed on the top side of the disinfection host.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the advantages of this invention are:

[0023] ① In this solution, the disinfection device combines an ultrasonic generator, a plasma generator, and a UVC radiation generator. Through the synergistic effect of physical factors (such as ultrasonic waves destroying the structure of microorganisms, plasma decomposing organic matter, and UVC inactivating viruses), it achieves highly efficient disinfection in seconds with no chemical residue. It is suitable for various scenarios such as medical treatment and food processing. Moreover, the three disinfection methods do not produce chronic toxicity, ensuring the safety of disinfection.

[0024] ② In this solution, the disinfection device has multi-mode spray control. Through independently controlled horizontal and vertical grid systems, controlled by the horizontal control structure and the vertical control structure respectively, it can realize three spray modes: up and down sweeping, left and right sweeping, and cyclic sweeping. This significantly expands the atomization coverage area, improves disinfection uniformity, increases the atomization area, and ensures the disinfection effect. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] Please see Figure 1 - Figure 4 An air and surface disinfection device using the synergistic effect of ultrasonic plasma and photo-oxidation includes a disinfection host 1. The disinfection host 1 has windows on the front and two sides. A fixed grille 2 is fixedly installed on the window on the front. A control panel 3 is fixedly installed on the top of the front of the disinfection host 1. An adjustable grille 4 is installed on the window on the side. An internal grille control component 5 of the disinfection host 1 controls the movement of the adjustable grille 4.

[0041] The adjustable grid 4 includes several horizontal grid plates 401 and two vertical grid plates 402. The horizontal grid plates 401 and the vertical grid plates 402 are vertically distributed in space, and there is no direct contact between any horizontal grid plate 401 and the vertical grid plate 402.

[0042] The grid control assembly 5 includes a horizontal control structure 501 and a vertical control structure 502. The horizontal control structure 501 and the vertical control structure 502 have the same structure. The horizontal control structure 501 controls the horizontal grid plate 401 to rotate, and the vertical control structure 502 controls the vertical grid plate 402 to rotate.

[0043] See Figure 3 , Figure 4 Specifically, the lateral control structure 501 includes a motor 5011, the output end of which is connected to a sector gear 5012 via a coupling, and the sector gear 5012 is meshed with a driven gear 5013.

[0044] A rotating shaft 5014 is fixedly inserted through the transverse grid plate 401. One end of the rotating shaft 5014 is fixed to the central axis of the driven gear 5013, and a torque spring 5015 is installed at the other end of the rotating shaft 5014. The torque spring 5015 is fixed to the inner wall of the disinfection host 1.

[0045] The lateral control structure 501 also includes several thin connecting rods 5016, each of which is hinged to two adjacent lateral grid plates 401.

[0046] Motor 5011 controls the rotation of sector gear 5012, and the meshing between sector gear 5012 and driven gear 5013 causes driven gear 5013 to rotate synchronously, thereby controlling the rotation of shaft 5014 and the rotation of transverse grid plate 401. At this time, torque spring 5015 further accumulates potential energy.

[0047] When the sector gear 5012 disengages from the driven gear 5013, the torque spring 5015 releases potential energy, causing the transverse grid plate 401 to return to its initial position until the sector gear 5012 and the driven gear 5013 re-engage, thus enabling the transverse grid plate 401 to repeatedly rotate.

[0048] Similarly, the vertical control structure 502 controls the vertical grid plate 402 to rotate repeatedly, and controls the working mode of the horizontal control structure 501 and the vertical control structure 502, which can effectively expand the orientation of the adjustable grid 4. By installing the atomizing structure inside the disinfection host 1 and close to the adjustable grid 4, the spraying area of ​​the atomization can be increased, and the atomization operation effect can be improved.

[0049] Specifically, the motor 5011 in the horizontal control structure 501 and the motor 5011 in the vertical control structure 502 are controlled by independent signals.

[0050] In this way, the two motors 5011 can be controlled to work independently without interfering with each other, and three modes of sweeping spraying can be realized: up and down sweeping spraying, left and right sweeping spraying, and cyclic sweeping spraying, thus improving the practicality of the device.

[0051] Specifically, the two motors 5011 are motors with electromagnetic brakes, and both motors 5011 are fixed inside the disinfection host 1.

[0052] When the motor 5011 stops rotating, the angle of the motor 5011 shaft can be locked, and finally the angle of the transverse grid plate 401 can be locked to achieve a fixed angle of spray. This can prevent the spray from avoiding the human body or prevent an object from being affected by the moisture of the spray.

[0053] Specifically, the number of teeth in sector gear 5012 occupies a sector angle of 120°.

[0054] When the sector gear 5012 rotates one-third of a revolution, the sector gear 5012 disengages from the driven gear 5013, and then, under the action of the torque spring 5015, the transverse grid plate 401 returns to its initial position.

[0055] By controlling the number of teeth on the sector gear 5012, the time for the transverse grid plate 401 to return to its initial position can be effectively preserved, thus ensuring the flipping angle of the transverse grid plate 401.

[0056] Specifically, in the lateral control structure 501, there are four thin connecting rods 5016 between two adjacent lateral grid plates 401, and the four thin connecting rods 5016 are parallel to each other and distributed in a square.

[0057] By using the thin connecting rod 5016 in conjunction with the hinged connection, when any one of the horizontal grid plates 401 rotates, all the horizontal grid plates 401 will rotate accordingly, and the rotation angle will be the same, which facilitates the synchronous control of the horizontal grid plates 401.

[0058] The control principle of the vertical grid plate 402 is the same.

[0059] Example 2:

[0060] Based on the above embodiment 1, further description is provided.

[0061] See Figure 1 Specifically, the disinfection host 1 is equipped with an ultrasonic generator, a plasma generator, and a UVC radiation generator.

[0062] Ultrasonic generators act on media such as light particles and plasma, and the resulting viscosity and thermal conductivity induce relaxation effects in the microscopic dynamic processes of the media, thereby causing drastic destruction of microbial structures and ensuring highly efficient elimination within seconds.

[0063] Plasma generators produce a large number of highly active substances in an excited state, such as H+ (H2O), O2- (H2O), and OH- (H2O), after high-frequency and high-voltage excitation. These substances can quickly kill bacteria, viruses, and other microorganisms, effectively decompose organic matter such as formaldehyde and TVOC, rapidly remove odor molecules, and purify the air.

[0064] UVC radiation is commonly used for disinfection of air, water, and non-porous surfaces. UVC radiation damages the outer protein coating of viruses, ultimately leading to viral inactivation. UVC radiation is also effective in inactivating bacteria and mold.

[0065] The synergistic effect of the three physical agents makes the disinfection process extremely rapid, significantly shortening disinfection time and improving efficiency. The disinfection process produces no chemical residues, is harmless to humans, and avoids allergic reactions and other health problems. Furthermore, the combined effect of the three disinfection methods is suitable for various scenarios, including food preservation.

[0066] See Figure 1 Specifically, a consumable inlet pipe 6 is fixedly installed on the top side of the disinfection unit 1.

[0067] When liquid consumables are injected from the consumables inlet pipe 6, they can be directly connected to the water pipe for filling.

[0068] To add consumables, you can directly add liquid consumables. After adding, press the medicine button at point 3 on the control panel to atomize and spray the liquid consumables.

[0069] This method makes it easy to add consumables.

[0070] Working principle:

[0071] The disinfection device is connected to a power source via an electric wire and is powered by it. When the device is working, the ultrasonic generator, plasma generator, and UVC radiation generator work simultaneously. The ultrasonic generator causes severe damage to the structure of microorganisms, ensuring efficient disinfection within seconds. The plasma generator can quickly kill bacteria, viruses, and other microorganisms, and can effectively decompose organic matter such as formaldehyde and TVOC, rapidly remove odor molecules, and purify the air. UVC radiation causes viruses to become inactive and can effectively inactivate bacteria and mold.

[0072] Simultaneously, liquid consumables are injected through the consumable inlet pipe 6. After atomization, the liquid consumables are sprayed out through the adjustable grille 4. At this time, the motor 5011 controls the rotation of the sector gear 5012, which, in conjunction with the meshing between the sector gear 5012 and the driven gear 5013, causes the driven gear 5013 to rotate synchronously, thereby controlling the rotation of the rotating shaft 5014 and the rotation of the transverse grid plate 401. At this time, the torque spring 5015 further accumulates potential energy. When the sector gear 5012 and the driven gear 5013 mesh... When disengaged, the torque spring 5015 releases potential energy, causing the transverse grid plate 401 to return to its initial position until the sector gear 5012 and the driven gear 5013 re-engage. This allows the transverse grid plate 401 to repeatedly rotate. Similarly, the vertical control structure 502 controls the vertical grid plate 402 to repeatedly rotate, controlling the working modes of the transverse control structure 501 and the vertical control structure 502. This effectively expands the orientation of the adjustable grid 4, increases the spraying area of ​​atomization, and improves the atomization effect.

[0073] This completes the use of the disinfection device.
